Abstract

The present invention provides a multiplex transmission apparatus that conducts a traffic control and a discard priority control on an ATM network 2 for transferring IP packets having a plurality of QoS conditions set therein. A multiplex transmission apparatus according to the present invention transmits an IP packet 3 to the ATM network 2. The multiplex transmission apparatus includes intermediately generated packet generation means 12 for generating an intermediately generated packet (CPS packet) having second header information "CID" based on first header information "DSCP" of the IP packet 3, buffer storage means 13 for storing the intermediately generated packet in any of a plurality of transmission waiting buffers 14, to 14n based on the second header information "CID", takeout means 16 for taking out the intermediately generated packet from the transmission waiting buffers 14, to 14, according to the second header information "CID", and ATM cell transmission means 17 and 18 for loading an ATM cell 4 with the intermediately generated packet taken out and transmitting the ATM cell 4 to the ATM network 2.
